    Thank you for the tip about the thermal compound every 6 months I think that will solve the problem completely

    does the fan work when you boots up your laptop.....overheating can also be caused if the environment u're working on is not conditioned enough

I would recommend cleaning out the vents and geatsink grills with compressed air. I would then remove the heatsink unnit and replace the thermal grease on the heatsink and processor. Most laptops do not need any additional cooling if thier heatsinks are free of dirt, dust and debris. The compressed air can be bought at office supply chains. Just use short bursts of air and clean all the compartments including the cd tray. Just make sure to power down the laptop first and remove the battery.

Testimonial: "I replaced my fan and it cools down now but I did not put the thermal compound on and my laptop spins the fan at an extremely fast rate until it shuts"

    When your fans "spools" up like that it means the processor's algorithym is telling the fan the the processor is hot and needs extra speed to cool it down and then shut off. I advise customers who use their laptops regularly to replace the thermal compound evry 6 months. It is cheap insurance.

I took my Compaq Presario laptop apart and I found that there was no heat transfer grease between the heat sink plate and the CPU?! There is a sensor built into the heat sink plate that controls fan speed and I believe that without the grease the sensor was not reading the correct temperature to regulate fan speed during cooling thus the constant lockups (CPU going into thermal shutdown). Make sure the spring-loaded screws are tightened down as well for good contact between the CPU and the heat sink plate. They should be indicated with numbers 1-4 on many Compaq laptops. Afterward, I ran several CPU tests and no more lock ups. This grease can be bought at any good computer store but use just enough to cover the chip and not too thick. I would only recommend this to someone who knows how to work on computers. Good luck!

Compaq Presario F700 keeps turning on and off


At this point I assume you've tried to go into SAFE mode, and into BIOS with no luck. You're right about the overheating but I think the damage is done. If the unit will no longer stay on in any mode or condition then heat has ruined something. First easiest part to check is memory. The check the CPU (most laptops still have a plug in CPU). If neither of these are suspect then take everything off the motherboard, including the screen (I use and external monitor). If the problem still exists then it's time to use a scope.
